As a result of some of the longish posts, comments, and replies about the architecture and functionality of DL4000s with deduplication that I engaged in with Curtis Preston and others, I got to thinking.
My feeling was that Curtis was wrong, but not for any specific technical reason.
Sure, some of his points were wrong in my estimation. Some were right.
But even accounting for that, I had the feeling that the sum of his argument was more wrong than right, and more wrong than I could account for by simply saying that this or that specific point was wrong.
Put another way: the whole of his argument was less than the sum of its parts.
But why exactly he was wrong is, I think, interesting.
Mr. Preston is wrong because the discussion is not relevant. Not cogent to why somebody might choose to buy a particular virtual tape library, or deduplication device. So ultimately, it comes down to not so much that he is wrong, but that the whole discussion fundamentally misses the point, and is not relevant.
It doesn't pass the "so what?" test.
